4 Information for electrically skilled persons
4.1 Fitting and electrical connection
DANGER!
Electrical shock on contact with live parts in the installation environment.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live parts
in the working environment.
General notes
Use data cable with 120 ohm characteristic impedance (e.g. CAT 5, 6, 7 network cable) for the
DMX bus.
Use a common wire pair each for the signals DMX In + / - and DMX Out + / -.
Do not use the terminal pairs DMX In and DMX Out to loop through a DMX signal. The terminal
pairs are only used individually depending on the operating mode.
Do not wire DMX bus in a star configuration.
Only use power supply units that supply secure extra low voltage SELV for power supply.
Connecting the device – operating mode "DMX master"
In the operating mode "DMX master" the gateway functions as a DMX data generator. The ter-
minals DMX Out and GND are used for connection to the DMX bus.
Connect a maximum of 32 devices per gateway.
Only a single data generator is permitted in a DMX system. In order to combine the gate-
way with an additional DMX data generator (e.g. a DMX lighting console), a so-called
"DMX merger" is required.
￭ Connect DMX bus to the terminals DMX Out + and DMX Out - (2) and GND (3).
￭ Connect KNX bus to the KNX terminals (7).
